To all whom it may concern.' Y

Beit known that I, MYRoN B. NUTE, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinventedcertain new and useful Improvements in Window-Ventilators, ofwhich the following isa specification.

My invention relates to improvements in window ventilators, and moreparticularly in that class of ventilators which are adapted to defiectthe air `from a window upwardly toward the ceiling of the ventilatedroom.

One of the'objects of my invention is to provide, an eiiicient simple,easily to .be ate tached, and removed, adjustable window ventilatorlwhich shall be cheap of construction and effective in operation.

Another, and more specific, object of my invention is to make the deviceof a light weather-proof material,`of sufficient rigidity and strengthto withstand the Work and wear imposed upon it, by daily use,.and yetinexpensive in character.

Other and further objects of my invention will become readily apparent,to persons skilled in the art, from a consideration of the following"description when taken in conjunction with the drawings, wherein Figurel is a view of an interior of a room, or apartment, showing theventilator in perspective, as it is applied toa window; Fig. 2 shows thedevice detached, with the hinged showing the same side as that seen inFig. l; Fig. 3 is a similar view showing the other, or outside of thedevice; Fig. 4 is a 4-4 of Fig.`2; Fig. 5

Fig. 2; Fig. 6 is an enlarged section taken on line 6-6 of Fig. 2.

nallthe views the same reference characters are employed to designatesimilar parts. i j i 10 is the inner wall ofan apartment, or. room,provided withawindow, of which 11, is 'the casing.

12 is a vertically `movable sash and 13 is the base portionof thecasing.

In Fig. 1 the ventilator is shown in such position that the sash may bevertically moved without disturbing the ventilator, and in this figurethe sash is raised higher angular end pieces open lat,and"

than it would be when in proper operative position, the view thusshowing more clearly the sash and its relation to the ventilator.- Y

` The ventilator consists, essentially, of two substantially duplicateparts 14 and 15,

each part terminating in a triangular piece 16, which is hingedlyjoined, `by proper articulation between the parts, in a substantialvertical line, to its respective main portions 14 and 15. The members,v14 and 15, are movably secured together in such way that they may belongitudinally extended and contracted `for the purpose of adjusting thelength of the device to windows of vary ing width. As heretofore stated,a cheap and efiicient device may be provided by the use `of corrugatedstraw boards or other like ber material, andin the making of the devicefrom such material it is advisable, as hereafter described, to protectthe raw edges by binding them with a suitable paper or fabric tape. Itis therefore advisable that the edges of the overlapping boards beleftfree and unmutilated and to this end my invention contemplates theprovision of slots 17 and 18 in one of the members, as in the interiormember 14, of the drawing, and cleats 19 and 20, the narrow portions 21and 22 of the cleats `respectively, are adapted for sliding movement inslots 17 and 18, respectively, and the cleats are held to the outermember, 15, by means of screws 23. By this means the members 14 and 15may bemoved longitudinally to the extent permissible by the slots 17 and18 and the cleats 19 and 20. For best construction and operation 1provide suflicient friction between the cleats and the contractingmembers, so that the parts will remain in the positions to which theyhave been adjusted to the end that it may be freely handled `withoutdisturbing the longitudinal adjustment of the devicer as a whole. Themembers 14 and 15 mayconveniently be made of `corrugated straw boards,or

other like fibrous material, comprising an `1nte`r1or,

corrugated member 24, and the outer fiat members 25-25 secured thereto,as by glue or the like. After the members 14 and 15 have'been cut fromthe material, each of the members are bound around the edges bysuifciently exible stout fibrous material, such as paper, fabric tape,or the like, and otherraw edges are protected in like manner as shown at26. The angular end members 16, are connected to their respective majorportions or members, 14 and 15, by a suitable articulate joint, repre-lsented by 27, whereby angular motion may occur between the parts in asubstantiallyvertical plane. lVhen the device is made of the materialwhich I have heretoforel described, the articulate connection betweenthe parts 16 and their respective major por* vtions, may be made byplacing a narrow, "thin, straight edge over the line 27 and by applyingpressure to the straight edge thereby providing a kerf in the parts 25and' the intermediate corrugated member 24, whereby to provide anarticulate hinge 'upon which the part 16may be moved.A

A For the purpose of attaching the device to the sides of the windowcasing I provide elongated slots 29, made in and near the top of each ofthe angular pieces 16, for attaching coperation with'the screwy eyes 30,

that may be placed in the sides of the window casing 11, `as a means forholding the device in position.

In applying the device to the window, the

ma]or portions, 141- and 15 are longitudinally moved until-,the endpieces 16 are separated a. distance equal to the distance between the'side parts 11' of the window casing. Then each part 16 is bent inwardlyslightly more than at right angles from their major lportions to whichthey are connected. In applying the device, the screw eye 30 is turnedso that the eye icfrtion is substantially parallel with the longest partof the slot 29. The slots 29 are then slipped over the screw eyes andthe screw eyes are then turned to anextent equalto about 90 as shown inFig. 6, whereby thedevice will be held in its proper position in thewin-V Copies of this patent may be obtained for the edges with tape, asheretofore described.

\ lWhen the device is made of paste-board,

the outside surfaces, including the binding is preferably treated with awater-proofingV material, such as a suitable varnish, or the like, so asto render it non-absorbent of moisture to give it sufficient rigidity,and to add to its sanitary qualities.

While my device is intended for permanent use, the ease with which it`may be attached and removed, renders it convenient forintermittent usein bed rooms, or other-sleeping apartments, whereit may be`frequentlyapplied and removed, and being `light in weight it may bereadily handled with but little exertion.

Y In the operation of the device, the windowA 12 yis raised an `extentequal only to about one half the vertical height of the deflector, sothat when the incoming air strikes the inclined surfaces` formed .by theparts 14 and 15, it is thereby upwardly deflected to a region near thetopv of the room, oi' near the ceiling, so that it may mingle with. thewarmer air, of` the apartment, or room,v before it descends to thebreathing line, and `comes in contact with the persons therein.

While I have herein described a single embodiment of my invention, forthe purpose of clear disclosure, it` isfapparent to persons skilledinthe art that many changes may be made withoutdeparting from the spiritand `scope of the appended claim.

lVhat I claim is.:

A window ventilator comprising two lapped longitudinally movable boards,end members secured Ito each 'of said vmovable boards, one of themovable,membershaving near its center, long narrow? slots, elongatedcleats of a width greater than that of theslots overlying theoutervedges of the slotted 4boards ,and extending lthrough theSlots,and-clips fastened near the outer' ends of thefsaidcleats andjoining them with the imper'forate member, thereby providing slidingconnections between the two ineinbers. l i

In testimony whereof I `hereunto set my hand in the presence of twowitnesses.
